present to Figs. 1 to 8 inclusive, '1 represents a convention alformor make of type-Writing machine, C "we reciprocating carriage thereof, and R the roller or platen over which the letter sheets L are passed and against which the type-bars operate, all as Well understood in the art. In the present embodiment of my invention, 1 secure to the carriage in any mechanical manner a relatively stationary horizontal frame F, said frame in the illustration being provided with depending'legs or members F at the inner or front corners thereof to effect connection with the carriage, said legs being in the present instance made preferably integral with the terminals of the carriage, whereby the frame F likewise be-. comes an integral part of the. carriage.

Mounted across .the medial portion of the frame F about an axis parallel to the axis of the roller R is a roll of copy paper or sheet 1, isv brought forward over the spring guides a on the machine and over the roller R, thence. rearward over a guide, or forwardly and downwardly inclined curved supporting apron 2 secured at its upper fixed end to the front face of a. flat metal strip or bar 3 set on an'incline, and provided with forwardly bent terminal arms 3, 3, secured to lugs 6 formed on the frame l .v ounted between the arms 3, 3", and spaced from the apron 2, is a rocl shaft 4 which projects at each end a suitable dis tance outside and beyond its points of sup- 'portin said arms 3, and is provided with a cranlcarm 5 at. each end. Secured to the rock-shaft 4 betweenthe members 3, and extending substantially the full length of the strip 3 is a cutter or blade 6 disposed in a plane at an obtuse angle to the plane of dis position of the crank-arms 5, 5, the latter by reason of their leverage and weight (as against that of the blade) normally drop-- ping to substantially a horizontal position and resting against the offsets h, h, formed in the frame F. I do not wish however, to limit myself to the obtuse angle here referred to. With the crank-arms 5 in their lowest or horizontal position, the shaft will'be rocked so as to oscillate the blade 6 sufiicientlv to clear the upper edge of the apron 2 (Figs. 3, 4) thereby leaving a clear space for the freeand uninterrupted travel therethrough of the sheet 1 afterleaving the apron 2, and asit passes onto and over the upper flexed guide strips 7, "Z, overhanging the roller 1 (and the roller S rearward thereof to be pr sently referred to), the fixed ends of said strips T being secured to the rear face of the strip, or bar 3. Mounted rearward of the roll 1 is a. roll of carbon or equivalent manifold paper the roll 8 being parallel to the roll 1. the sheet therefrom being likewise brought :lorward over the springs or guides o, between said guides and the sheet 1, whence the sheet is brought over the roller 1h. in front'of the sheet 1 and between the latter an t the usual: original or letter sheet L against which bears the ink ribbon t through which the impressions on said sheet L are .made as well understood in the art. The sheet L must. obviously be inserted from rear forwardly, between the guides a, and. roller R. so that the sheet 8 will come be tween the sheets L and 1. As well understood in the art rolls on the order of l. and 8 are usually provided with roller core pieces or cylii'iders P and S, respectively, terminating in Sl'JlIlCllQS 10. 10. In the present mounting the spindles 10 have bearing against them the free ends of suitable spring arms ll, ll, whose fixed ends are secured to the frame I. said springs operating as brakes to prevent the rolls'from turning too freely, and hence at all times imposing the proper tension on. the sheets as they are drawn through the machine. The free ends of the sprh'tgs ll tern'tinate in loops 11' by which they may be manipulated to release the spindles. In front of the machine the several sheets pass between the roller or platen R and a guide roller in already present in the machine, the sheets 1 and S separating and being independently guided after leaving the roller 27; and platen l't.

livot'ed between the Sit es of the frame F in front of the oti'sets 72., It, an oscillating frame N in the form substantiallyof an inverted U, the arms of said oscillating or tilting frame having formed suitable olfsets n, n, at points adjacent the pivotal axis of the frame. To the opposite faces of these o'l'lsets are secured the fixed ends of the tripping arms or tappets 12, 13, respectively, the lower arms 13 being the longer and terminating in upturned. hooks 33 as shown, each pair of arms (12.13) being disposed substantially in the same vertical plane. dhen the frame N oscillated rcarwardly the arms 12 bear against: the crank-arms 5 of the 5 roclcshaft .4 of the blade 6, thereby arresting any further rearward oscillation of the frame and likewise preventing accidental. depres 1 sion or rearward oscillation of the blade; and

when the frame N is oscillated foiwrm'dly the arms 13 (which diverge at a suitable angle from th 2 arms '12) trip the eranlt arms 5 upwardly (see dotted position Fig. 4) thus rocking the shaft. 4 in proper direction to cause the blade 6 to oscillate rearwardly and bring the cutting edge of said blade in firm A contact with the sheet 1 and the upper edge of the supper-tin apron 2 over which said sheet passes on its way to the flexed guides 7, 7. The forward or outward oscillation of the frame N is limited by the hooks 13 which grasp the ends of the already elevated crankarms (Fig. 4c, dotted position).

itlounted detachal'ily on the frame N in any well known manner known to the art for mounting rollers, is a roller S corresponding to the core S of the carbon paper roll 8, the sheet 8 after leaving the platen R passing over said roller S and 'inding the sheet 8 thereon as fast as the same unwinds from the core 55, the sheet passing over an intermediate roller or idler 14 as shown. As well understood in the art the sheets L, 8 and 1 are advanced through the machine by the periodic advances or rotations of the roller or platen R, the amount or degree of advance depending on the size of spacing between consecutive lines. So far as the sheets L and l are concerned, these are fed through the machine by the periodic rotations of the roller R accomplished manually by the operator manipulating the type-writer; but the carbon paper sheet 8 which is used until no longer available must be wound on the roller S as it unwinds from he core S. To impart to the roller S a rotation which shall respond to the periodic advances of the sheet 8 by the roller P, some provision must be made to drive the roller S. This is accomplished by the following mechanism :-On the right hand side of the frame N is a spring actuated clock mechanism mounted in a housing or frame (which by the way serves to supportthe spindles s, 14', of the rollers S and 14; respectively). In said housing is mounted a shaft or Winding arbor 15 adapted to be manipulated by a key K, said shaft having keyed thereto a ratchet pinion 16 with which cooperates a spring-controlled pawl 17 pivoted to the adjacent face of a gear wheel 18 mounted loosely on the shaft adjacentto the ratchet pinion. a second gear if) at the opposite end of the shaft being likewise mounted loosely on said shaft. Botween the gears 18. 19 is a driving spring 20 whose inner end is secured to the shaft. the outer end being secured to the adjacent face of the wheel 19. The wheel 18 meshes with a pinion 91 on the spindle s of the roller S. the gear 19 in turn meshing with a pinion 22 on the spindle 14" of the roller 14. From the connections described it will be seen that when the spring 20 is wound (the winding being accomplished. by turning the arbor or shaft 15 clockwise by means of the hey IQ it will drive the gear 18 in one direction (Fig. and the gear 19 in the opposite direction (Fi n 7) the respective gears being loose on the shaft 15. Of course,- the gear 18 being connected to the ratchet 1G exerted on the stretch of web ehroughthe pawl 17 will naturally move in unison with the shaft 15 as the latter un winds under the influence of the drivespring-20. The gears 18, 19, thus turning in opposite directions will impart rotations in opposite directions respectively to the rollers S and 14" (Fig. 4). Either ear 18, 19, may be locked against rotation t rough the medium of a tooth or process w, on a slide or brake-bar 23 polygonal in cross-section sliding through a corres onding opening in the. side of the frame hi: an inward movement of the slide forcing the tooth w across the space between consecutive teeth on the gear and hence lock the gear against rotation. The outer ends of the slides 23 are provided with finger-holds 23 for manipu lating the same. In Fig. 2 it will be seen that the gear 19 is shown as locked against rotation thus preventing the idler roller 14 from turning. The object of arresting either gear against rotation as here indicated will be brought out in the description of the operation of the device to be presently given. The axis of oscillation of the frame N being eccentric to the axis of the roller R over which the sheet 8 passes, it follows that when said frame is swun to its forward dotted position in Fig. 4 to drive the cutting edge of the blade 6 against the apron 2) the roller S will'beat a greater distance rom said axis (of the roller R) and consequently more or less tens ion will be or sheet 8 between the members R and S.

. or pull will naturally impart a rotation to "oscillation forward by the arrest of the .ing a pinion 25 on the rock-shaft the roller S in a direction opposite to that in which it is normally driven by the spring 20, and against the tension of said spring, but since the spring is not a owerful one, it will readily yield to the pull thus exerted on the Web 8, the gear 18 and arbor 15 under the circumstances having imparted thereto a slight reverse rotation or in a direction ops posite to that indicated by the arrow in Fig. 6 (see dotted arrow in dotted position of the parts in Fig. 4).

In lieu of the tripping members 12, 13, for rocking the shaft 4, I may provide the frame N with a, toothed segment 24 engagof the blade 6,-as shown in the'modification in F ig. In that case the blade 6 is set at such an ;;.-gle that by the time the frame N has swung forward through an arc correspondmg to what it describes in Fig. 4', the pinion 25 and shaft4' will have rotated sufficiently to cause the edge of the blade to forcibly engage the upper edge of.the apron 2, the frame N being arrested against any further blade againstthe apron, the segment 24 remaining in permanent mesh with the pinion 25. A return of-the frame N will of course, restore the parts .to normal position I a The web lis conducts R done manually b This tension .as indicated in said Fig. 9. sue the frame isli mited by the the frame F. l The operation may be dose erence to Figs. 1 to 8 incrisi stantially as follows :--The sheet or letter paper L is roller R from rear forward as r 3, 42), the webs i and 8 has viously passed over the roller spective rollers P, S, in the or on the drawings that is to ay 'bon web 8 between the s rearward along a is in n an i through the slot space between to 6 and the upper edge of the apt just pref'ct beyondthe m tt p is passes over the-guide refit over the win-" ng rolier S. withithoperiodicg advances or rotations of the roiler platen the operator as well erstood in the art ithe-serergiiyvebs ii, 8, 1, will be advanced accordinghy; hut inasmuch as in the present em eat oi invention I employ a, shoe which must he wound or it unwinds from roller end, suitable provision ran an automatic winding there s as advanced by the, roller :33. This wii-e....-.. o the carbon sheet is accompiished by the turn ing'oi theroller S under the driving action of the spring 20 as already descrihed,-the 4 springautomatically takin up the slack the sheet (8) with eacha vance thereof by the roller R, by the drivin of the roller S in theproper direction. The operation as described assumes that the ar'i is locked, against rotation by the toot 1w of its corresponding slide or brake-bar 23- (Fig. 2) whereby the idle "roller 14 remains stationary, the sheet 8 simply slipping over it. 'After a letter or other writing on the sheet has been completed, the copy sheet 1. 119 which by that time has been advanced a greater or less distance beyond the blade 6 and over the guides Z, 7-, is torn off or sea ered by swinging the frame N forward to the dotted position indicated in Fig. 4-, the oscillation of said frame in the direction indicated causing the arms 13 to trip the crank-arms 5, 5, upwardly and thus force v the edge of the blade against said sheet '1'; and against the upper edge of t W'th the 'edge of the blade thus bearing ag inst the copy sheet, a clean cut 'ofjlie sh et may be made tbyrsimply drawing the sh et along the edgev ofthe blade. The severed section thuscont-ains a carbon copy of 3' the letter or communicationor other writing impressed on the sheet L. and may be filed away for-future reference.

Shouldit be desired to preserve the carbon copies or manifolds on a smgl'e roll or that event the gear 19 is released. by dis- /:ngagi11g the tooth w therefrom, leaving the spring to rotate the gear in the direct ion 1 indicated by the arrow in Fig. 7. This will have the effect of turning the roller 14. counter-clockwise (see dotted arrow Fig. 4) whereby as the web 1 is periodically ad- ;vanced by the roller R it \vill'be automatii cally wound on the roller 14, and the entire repord of all carbon copies be thus preserved in roll'form. The turning of the roller it and the winding thereon of the sheet l Will' in no wise interfere with the passage there- 1 p sheet separating from the manifold sheet over of the sheet 8, the friction being insuliicient to afi ectthe free travel of said sheet 8.

Where the record of the carbon copies of, letters is thus preserved in roll form, the occasion does not arise to tilt the 1 frame N forwardly, the latter remaining in its rearwardly inclined position as indicated in Figs. 3 and 4. After the carbon sheet 8 hasbecn wholly unwound from the roller or core Sand wound on the roller 5, the rollers are removed from their respective frames, after which the full roller S is deposited on the frame F, and the empty roller S on the frame N, the carbon sheet being brought around so as to now wind on the roller S and unwind from the rolh-r copy material. respectively, said sheets be S. In this way the same sheet of carbon can be passed back and forth a number oi times through the machine until the copy- 'ing coating thereof is exhausted. in

carbon paper to reverse its travel through the machine as indicated, the gear '18 is locked temporarily against rotation by shoving in the slide oppositethereto until the rcmoving the rollers S, S, for the purpose:

of mounting-the same to cause the web of porting member for the copy sheetafter its scription in the present connection.

Having described my invention, What I,

claim is 1. in eon'ihination with a type-writer carriage and its platen, meanson the carriage for the support of sheets of manifold and copy material respectively, said sheets being adapted to be jointly passed over the platen, and advanced thereby, the copy upon leaving the platen, means for guiding and supporting the ccpy sheet after its separation from the i'i'ianifold sheet, a cutter movably mounted adjacent said guiding and supporting means to cooperate therewith, a-

gea r wheel.

Unless this were don thef spring 20 \vould'unwiml itself \vhilc the change in position of rollers was being made because there would be no rcslslan c offered to the rotation of the gears. This unnecessary unwinding of course, is undesirable, and

for this reason the gear 18 lockeduntil the rollersS, S, are reset.

Where the cutter (i is availed of for sever- .ing the copy sheet 1 at the end of each letter written, the apron 2 su 'iports the portion ofthe sheet which is beyond tlieroller lt and below the section to be severed whi h is beyond the cutter) so as to leave the. free end of said ortion substantially -flpsh with the upper e ge of the apron, whence it will readily feed over the members 7. T, vvith subsequent advances of the roller it.
